When Apple introduced the new MacBook Pro, the company also introduced a new 140-watt USB-C charger that comes in a box with 16-inch models. Although it looks like any other ordinary charger, Apple’s 140W charger is the first made by a company with gallium nitride (GaN). Now the disassembly shows all the details of the new 16-inch MacBook Pro charger.
YouTube channel ChargerLAB shared a video showing the entire process of disassembling Apple’s 140W USB-C charger. What makes this charger interesting are its new technologies, as it uses the USB-C PD 3.1 standard that can deliver up to 240W of power. In addition, this is also Apple’s first GaN power adapter.
Gallium nitride, or GaN, is a material used for semiconductors that produces less heat. As a result, the components can be brought together, and the charger can be more compact without affecting its safety. To achieve maximum 140W of power when charging your MacBook, a new USB-C cable to MagSafe 3 is required as there are still no ordinary USB-C cables compatible with the new standard available on the market.
Moving on to disassembly, ChargerLAB shows that there is no easy way to disassemble an Apple charger. They had to cut a hard plastic shell to gain access to the internal components of the power adapter, which would of course cause permanent damage.
When the charger is disassembled, we can see a fairly solid structure inside. The plastic shell is really thick and there is black glue to keep the main module fixed. As noted in the video, there are also multiple thermal adhesives and graphite thermal pads on top of the chips for heat dissipation and protection.
For those who want to know every detail about Apple’s charger components, ChargerLAB’s video shows a detailed look at what each component does – including the new GaN chips. You can watch the full video below:
